Distribute index cards and markers. Set a topic, e.g. one of the following:
How did you feel during the iteration?
What was the most remarkable moment?
What was the biggest problem?
What did you long for?
If the last iteration had been a circus performance, what part did you play? Juggler, funambulist, clown, knife-thrower, ...
Ask the team members to draw their answer. Post all drawings on a whiteboard. For each drawing let people guess what it means, before the artist explains it. Metaphors open new viewpoints and create a shared understanding.
Collect events when team members felt mad, sad, or glad and find the sources Source:
Put up three posters labeled 'mad', 'sad', and 'glad' (or >:(, :(, :) alternatively). Team members write down one event per color coded card, when they've felt that way. When the time is up have everyone post their cards to the appropriate posters. Cluster the cards on each poster. Ask the group for cluster names. Debrief by asking:
What's standing out? What's unexpected?
What was difficult about this task? What was fun?
What patterns do you see? What do they mean for you as a team?
Asking and answering go around the team circle - an excellent way to reach consensus Source:
Everyone sits in a circle. Begin by stating that you'll go round asking questions to find out what you want to do as a group. You start by asking your neighbor the first question, e.g. 'What is the most important thing we should start in the next iteration?' Your neighbor answers and asks her neighbor a related question. Stop when consensus emerges or the time is up. Go around at least once, so that everybody is heard!
Let team members appreciate each other and end positively Source:

Start by giving a sincere appreciation of one of the participants. It can be anything they contributed: help to the team or you, a solved problem, ...Then invite others and wait for someone to work up the nerve. Close, when no one has talked for a minute.
